Figure 13 Average Annual Wet Depositions of SO4 (kg/ha) 1981-86 reduced by the removal of approximately 30% of the sites. Site selection for removal was based on an objective analysis, so that data quality will not be compromised. As an example, Figure 13 illustrates the sulphate deposition pattern calculated for the province with all sites included, and with the selected sites removed. D.

OXIDANTS STRATEGY DEVELOPMENT An oxidant control strategy document was completed during FY 89/90. The report supports the Ontario initiatives already being considered to reduce oxidant precursor emissions (NO, and VOCs). These initiatives are the Clean Air Program (CAP) and the Vehicle-related Emissions Strategy. CAP is aimed at the control of all stationary source emissions, including both NO, and VOCs, as well as air toxics, and will address emission reduction through the application of control technology for the protection of the air environment. The vehicle-related emissions strategy will reduce evaporative emissions through lowering of summer gasoline volatility and through the control of emissions during the distribution of vehicle fuels. Reductions will also be achieved through an active inspection and maintenance program. As an integral part of the program, Ontario supports the Federal initiative to adopt the 1993 California emission standards. Other initiatives, under development cooperatively with other Ministries, include: alternate fuels, changing transportation demand and improved efficiency. In addition to the above. Environment Ontario has been an active participant in all phases of the NO,A^OCs Management Plan developed by the Long-Range Transport of 13.
